Abstract

L'invention concerne un procédé de modulation de largeur d'impulsion pour commander la puissance de sortie d'un laser pulsé à gaz alimenté par une alimentation radiofréquence pulsée, ce procédé comprenant la transmission d'un train d'impulsions numériques à l'alimentation radiofréquence. Chaque impulsion du train a une durée incrémentalement variable. L'alimentation est configurée pour fournir un train d'impulsions radiofréquence correspondant en nombre et en durée au train d'impulsions numériques reçu. On peut modifier la puissance moyenne dans le train d'impulsions radiofréquence en faisant varier incrémentalement la durée d'une ou de plusieurs impulsions numériques dans le train d'impulsions numériques. Le train d'impulsions radiofréquence est utilisé pour alimenter un laser à gaz. Le laser à gaz sort un train d'impulsions correspondant au train d'impulsions radiofréquence.
